You won't get final model from it, but pretty close to it. I'm using it only for creating geometry, not interested of features like animation, wind, aging etc.
You can make model (didn't made lods), proper unwrapping, foliage distribution, materials and ID assigning in plant factory itself. You have control over almost everything. Individual branch, leaf. It handles quite ok external meshes and you're still able to modify them by nodes.

Plant factory is pretty handy tool especially on a big scale, when you want to make fast many variation of the same kind of tree. If you want to make just a one tree of each kind. Well... you probably won't save so much time.
Main disadvantage imo is performance of the application and stability.

At first it looks like you can make and sell to an only buyer (a company for example) statc meshes. Then it tunus out the content still have limitations and obligations for such buyer too like showing a credit on title screen.

A thing you couldn't ensure actually so how could it be your agreement violation?
